Vegas and free booze at poker table question

[Granite]

I like booze and I like gambling.

In Australian casino's your lucky to get a free coffee. With my first trip to Vegas soon I don't want to look like an idiot with my booze requests. Say I'm playing mid stakes poker can I order pretty much anything from the bar?

Thanks for the help with my noob question. I also plan on getting some time in at a couple of the LA rooms, would it be the same at the Commerce and Bike?

Cheers!
